A Ford Explorer with a mother and baby inside crashed into the back of bus No. 402 Tuesday around 7 a.m. on Memphis Bluelick Road near Interstate 65.

West Clark Community School's transportation director, Chad Schenck, said it happened while the bus was stopping at a home to pick up two students.

Schenck said the bus' stop sign went out but the Explorer behind didn't stop.

Thirty-one students were on the bus, ranging from elementary to high school age.

While most were taken back to school, 10 of them were taken to the hospital -- some to Kosair Children's Hospital and others to Clark Memorial Hospital.

"We had a total of 10 students taken for precautionary measures complaining again of some bumps and bruises," Schenck said.

The only sign of an accident on the bus was a bent rear fender, but Schenck said that helps put the force of the impact into perspective.

"It is very difficult to bend those rear fenders.This actually caused it to buckle in about 18 inches, so that was a substantial impact and didn't see any skid marks that would have shown braking before impact," Schenck said.

No one in the Explorer was hurt.

Authorities have not confirmed what caused the crash, but Schenck said he spoke with some witnesses who saw what happened.

"We had a couple parents that were at a residence and watched the school bus turn on her amber and flashing lights and engage her stop arm," Schenck said.

The driver of the bus was given a drug and alcohol test as standard.

Schenck warns with school now back in session, people should keep an eye out for stopping buses.

Parents were alerted after the crash and the school has counselors on-hand for students.
